[Asterisk-Users] Special Delivery from China

[James H. Thompson]

There are lots of GPL 8051 tools
Try a google search:
    8051 gpl

For example:
http://sdcc.sourceforge.net/
SDCC is a Freeware, retargettable, optimizing ANSI - C compiler that targets the Intel 8051, Maxim
80DS390 and the Zilog Z80 based MCUs. Work is in progress on supporting the Motorola 68HC08 as well
as Microchip PIC16 and PIC18 series. The entire source code for the compiler is distributed under
GPL.
